Hi I am 2 days late. I have been having very mild cramps of and on ,no dragging sensation which I normally get when AF due. This morning I had a very very light positive on preg test. Since the test I have had very small amount dark brown discharge. It varies between thick jelly like and stringy and watery but its not getting any heavier or changing colour. Any ideas? I have not been on birth control for 3 years.
